Avcodec decoder error more than 5 seconds of late video - Исправление ошибок и поиск оптимальных решений проблем

With the VLC 0.9.5 i am unable to play .mkv videos.

I get the following information :No suitable decoder module:
VLC does not support the audio or video format «undf». Unfortunately there is no way for you to fix this.

it is a mkv with a h264 video codec (1280X576) and a vorb audio codec (44.100 khz) inside.

Some more messages on the console screen :

[00000643] main decoder error: no suitable decoder module for fourcc `undf’.
VLC probably does not support this sound or video format.

Strange that i can see a still picture of it before the message appears.

The old VLC (0.86e) playes this file fine.

P.S.
Computer too slow can’t be the reason, since XINE,Mplayer and OLD VLC playes this file fine.
System is a AMD 2600 X2,4 GB RAM,NVidea 9600 Graphic Card.

I’m muxing mpeg4 video to avi container. The video stream is ~4fps, so I set AVCodecContext time_base to 1/4 (formatContext->streams[0]->codec->time_base…) , and then rescal each frame timestamp, because the original time-stamps are in milliseconds. The resulting value I assign to a packet pts and dts.

When I play this avi with VLC, the video is not smooth, and I get the following message repeatedly:

avcodec error: more than 5 seconds of late video -> dropping frame
(computer too slow ?)

Is there something wrong with the above pts/dts calculation?

The following table demonstrates how the timestamps are rescaled (original->rescaled)

When I start playing this video with vlc, it starts playing fine for 5-6 seconds, and then I get suddenly:

...
[00007f066cc1bad0] avcodec decoder error: more than 5 seconds of late video -> dropping frame (computer too slow ?)
[00007f066cc1bad0] avcodec decoder error: more than 5 seconds of late video -> dropping frame (computer too slow ?)

[00007f066cc1bad0] avcodec decoder error: more than 5 seconds of late video -> dropping frame (computer too slow ?)
...

I think also, the video at that point was showing a still frame for quite a long time (screen capture from a PC desktop), so it’s quite possible the capturing process did not insert keyframes there or something.

So, I was wondering, is it possible to fix this kind of an error message without reencoding (in ffmpeg that would be -vcodec copy), aside from inserting keyframes if that is necessary (though I’m not sure, maybe inserting keyframes does count like re-encoding in greater extent than -vcodec copy?)? If not, what would be the best way to fix this problem with ffmpeg, so I end up with minimal changes in existing quality?

vlc problems. [solved]

using stock archlinux ffmpeg and vlc packages (nothing rebuilt from aur or whatever), I’m getting problems outputing videos. flv videos work find but other videos give «[0x933310c] avcodec decoder error: more than 5 seconds of late video -> dropping frame (computer too slow ?)»
I have a nvidia 430GT card and a /proc/cpu says model name : Intel(R) Core(TM)2 CPU E7500 @ 2.93GHz
3GB ram.
so it should at least be able to handle videos.
how can I tell what’s wrong?

Re: vlc problems. [solved]

Make sure it’s set to use VDPAU accelleration: https://wiki.archlinux.org/index.php/NV … 2FVAAPI.29 (though with that CPU it should be fine either way…oh well). I have a GT430 and when I play any videos they play perfectly smooth with almost no CPU usage sine it uses VDPAU, should be the same for you. Also, you could try using mplayer (or Smplayer if you want a GUI) with its VDPAU output, I find that Mplayer better supports VDPAU than VLC does.

EDIT: Also make sure you have the libvdpau and vdpau-video packages installed, I’m not sure if they come as dependencies or not, better double check.

Re: vlc problems. [solved]

vdpau-video and libvdpau are installed.
I have «Use GPU acceleration» turned on.
BTW, this doesn’t happen when I ffplay files. It only fails with vlc.

Re: vlc problems. [solved]

I lifted this from readthefuckingmanual.net after a quick google so you may have already tried it. If not, you can try increasing vlc’s cache size for files as such:

*go to Tools->Preferences
*show settings All
*double click Input / Codecs
*double click Access Modules
*select File and increase the cache size.
*save and restart vlc

Also, what output do you get from vainfo?

Hi chr0nik. That seems to have some effect. I increased the cache size to a really huge number. 100000ms. now it plays a full second before it stops again

Also, what output do you get from vainfo?

Re: vlc problems. [solved]

I finally fixed this.
I recompiled vlc with —disable-libmpeg2 and now it uses ffmpeg to play mpg files instead of libmpeg2 and the problem is gone!

You aren’t supposed to start GUI applications from the command line. The message clearly tells you to use cvlc for that.

What happens when you try to play the flash video after starting vlc from the menu?

That’s a very common troubleshooting technique. As long as sudo isn’t involved, there shouldn’t be any issues. And this is often the only way to find the errors that are preventing the application from working properly.

That’s fair enough, and I’m aware of that, but in the absence of the poster not telling us why it was started from the command line, I’m not making the assumption that it was a deliberate attempt to get error messages. Also, .flv files are prone to that kind of error. They’re a terrible vehicle for videos.

Say more regarding your install of VLC. Did you install the mint-meta-codecs package? Check in Synaptics if this is indeed installed.

Everything is difficult before it gets easy.

That’s fair enough, and I’m aware of that, but in the absence of the poster not telling us why it was started from the command line, I’m not making the assumption that it was a deliberate attempt to get error messages. Also, .flv files are prone to that kind of error. They’re a terrible vehicle for videos.

Yes I started this from the command line to get the errors. If I reboot the machine, VLC starts working just fine. After 2 3 days (several suspend and start ) it stops working and again I have to reboot to rectify this problem

Say more regarding your install of VLC. Did you install the mint-meta-codecs package? Check in Synaptics if this is indeed installed.

I installed VLC from the Software Manager. mint-meta-codecs is already installed. I checked it in Software Manager.

After I reboot, VLC and YouTibe both would start working but after a day or two it would stop working again. Then, I run VLC on the command line, I get the following error:

$ vlc

[0000562c00a1b400] vlcpulse audio output error: PulseAudio server connection failure: Connection refused

Moreover, on FireFox YouTube shows video working fine but without the sound

In Chrome neither the YouTube video nor the sound works

That’s an abandoned PPA as you pointed out to another user not so long ago who suggested it…

The VLC versions offered are anything but current.

What does the command pulseaudio -k return when you don’t have any sound in the browsers.

What exactly stops working in VLC? Just the sound or something else?

Oh, apologies to the poster. I’ll fix it. Thank you for the heads up.

Thanks — no output means that pulseaudio is working. Can you check your home folder for any files not owned by you as a user with this command.

So, it only «goes bad» after some days, sleep/wake, etc. Any docks, desklets, conky, cinnamon-spices, etc, or vlc add-ons? Seems it could be a tricky one to chase out.

Instead of rebooting though when you encounter the problem try this:
open a terminal and run:

then retry vlc—does it work now without a full reboot?

Everything is difficult before it gets easy.

I googled dbus. From Wiki :

D-Bus is an IPC mechanism initially designed to replace the software component communications systems used by the GNOME and KDE Linux desktop environments

It shows permission denied for /home/mason/.dbus Is it normal ?

I tried it. and I get —

vlc: no process found

When I reboot, I get a message PulseAudio not responding. So I think culprit could be PulseAudio. I have uninstalled VLC and Celluloid both. I will report back in a few days if I still get YouTube not responding in browser.

Hi all,

my goal is to display a RTSP camera stream but VLC freeze, it show an image instead of the stream.

I’m using a :

RaspberryPi2 model 2
Raspbian Jessie
GPU_MEM=256
Overclok to Pi2, the max
RTSP Camera resolution 1920×1080
VLC media player 2.2.0-rc2 Weatherwax (revision 2.2.0-rc1-118-g22fda39)

With the minimum resolution of 1280×720, instead of 192×1080, it’s working but if I resize the screen of VLC, it freeze.

Code: Select all

vlc rtsp://user:password@192.168.1.166:554
VLC media player 2.2.0-rc2 Weatherwax (revision 2.2.0-rc1-118-g22fda39)

VLC is taking between 100% end 200% of CPU usage and 11% of memory. VLC is working well on my computeur with the same RTSP camera.

Is it a cpu/mem ressources issue? http://raspberrypi.stackexchange.com/a/22525

VLC (or mplayer) aren’t capable of playing back much on the Pi; they’re not optimized for videocore GPU, so they’re trying to do everything on the CPU (which is nowhere near powerful enough for video decoding). You can try playing back with omxplayer (which is) but I don’t recall whether it’s capable of playing back a network stream (probably possible with netcat or something similar).
I’ll add a note to the docs for 1.7 that VLC/mplayer should be run on a «normal» machine, not the Pi.

Thanks for your help

mpv version and platform

macOS Sierra 10.12.6

mpv 0.28.0-289-g13b90bc Copyright © 2000-2018 mpv/MPlayer/mplayer2 projects
ffmpeg library versions:
libavutil 56.7.101
libavcodec 58.11.101
libavformat 58.9.100
libswscale 5.0.101
libavfilter 7.12.100
libswresample 3.0.101
ffmpeg version: N-45682-gacdea9e7c

Reproduction steps

Create a rtp stream with a custom framerate (3 fps for example). Other framerates behave quiet similar (<25 fps). Playing a stream with 30fps is fine.

gst-launch-1.0 -v videotestsrc ! video/x-raw,width=640,height=480 ! videorate ! video/x-raw,framerate=3/1 ! x264enc sliced-threads=true tune=zerolatency speed-preset=1 ! rtph264pay ! udpsink host=127.0.0.1 port=5004

Play the stream using a sdp file:
rather simple sdp file: http://sprunge.us/HLHh

mpv --no-config --log-file=output.txt test.sdp

I tried disabling caching but the behaviour is the same:
mpv --no-config --log-file=output.txt --demuxer-seekable-cache=no --cache=no test.sdp

Expected behavior

Plays the stream with the given framerate.
VLC plays it fine.
ffplay plays it fine:
ffplay -loglevel debug -i -protocol_whitelist rtp,file,udp test.sdp

Actual behavior

Decoding breaks after a few seconds with decoding errors, artefacts and choppy playback
